Is there something wrong with the queue? UPD: Its fine now :)

Why do the ratings take ages to update in some rounds? Ratings of round 685, 686 and 687 haven't been updated since so many days.

Hi, Can anyone list all fenwick tree problems from particularly codeforces upto 2000 rating. Thanks.

Is something wrong with the queue?

Hello guys!

In yesterday's round Codeforces Round 617 (Div. 3), in question 1296C - Очередной идущий робот, I submitted this solution using map which took 61ms to pass: 70273184. Today, I thought of submitting the same solution using unordered map, which I later found out doesn't have a hash function for pairs, so I copied the hash function from GeeksForGeeks and then submitted the solution which took 187ms to pass: 70355416.

Can somebody tell me why is unordered map working slower than map for this problem ?

Thanks.
